Fast Super-Paramagnetic Clustering

Super Paramagnetic Clustering of Data (spc)

1 Summary A new clustering algorithm named Super Paramagnetic Clustering (SPC) which was published by Blatt et al. 1]]2]]3] is described. The algorithm, which was rst motivated by properties of inhomogeneous magnets, is described as an outcome of a general technique to create robust clustering algorithms. The technique uses a clustering cost function and nds the average custering solution at di...

Super-paramagnetic clustering of yeast gene expression profiles

High-density DNA arrays, used to monitor gene expression at a genomic scale, have produced vast amounts of information which require the development of efficient computational methods to analyze them. The important first step is to extract the fundamental patterns of gene expression inherent in the data. This paper describes the application of a novel clustering algorithm, Super-Paramagnetic Cl...

Polyethyleneimine-modified super paramagnetic Fe3O4 nanoparticles: An efficient, reusable and water tolerance nanocatalyst.

Polyethyleneimine-modified super paramagnetic Fe3O4 nanoparticles: An efficient, reusable and water tolerance nanocatalyst.

A novel magnetically immobilized polyethyleneimine (PEI) fabricated by covalently anchoring on silica coated Fe3O4 nanoparticles (PEI@Si-MNPs) was prepared. The synthesized catalyst was characterized by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). The immobili...
